A company has been working the past couple years developing a metal magazine for the LWRC SIX8 and other potential receiver sets to be made using said magazine.

Let's say they have the full support of LWRC, so that concern is out of the way.

Let's say they have finally successfully had said magazine designed by large magazine manufacturers.

Let's say they have CAD's for 10, 20 and 30 round capacities on hand.

Let's say they designed two versions - one for the 6.8SPC case body, and one for the 6.5 Grendel case body.

Let's say this company brought a functional 3D printed model of this magazine with them to the 2019 SHOT show, met with some very large Ammunition and Firearms manufacturers, showed it to them, and all were supportive.

Let's say they have production bids and schedules from a couple large, well known magazine manufacturers.

Let's say that there are additional compatible receiver set manufacturers lined up and ready to produce receiver sets that are compatible with the new metal magazine, as well as the original Magpul SIX8 Pmag.

Let's say that these additional receiver set manufacturers have sets priced at $350 or less.

Let's say one company already released their version of the compatible receiver sets and sold out in a couple weeks.

Let's say that the nominal Cartridge Overall Length capability of the magazines is 2.390", and that the published COAL will most likely be 2.380" to account for manufacture anomalies.

Let's say that said company has developed a new line of cartridges designed to take full advantage of the new COAL, and has dropped hints sporadically over time eluding to such.

Let's say that many other existing cartridges like the 6.8SPC, the 224 Valkyrie, 22 Nosler, and 6.5 Grendel will all be able to take advantage of the increased COAL in some capacity (Load Long), without having to "window" mags, providing full mag capacity at the long lengths.

Let's say that if one (the large ammunition companies and individuals) were so inclined, using the parameters these magazines would provide by design, that a cartridge with 40 grains H2O case capacity running at 55k PSI MAP would beat current 6.8SPCII and 6.5 Grendel numbers by ~200 fps could easily be designed.

Let's say said company owns the magazine designs, that they are patent pending, dozens of NDA's are in place and that production could start as soon as the tooling is paid for.

Let's say that we all understand what this new development is capable of turning into; how an entirely new family of cartridges would be developed to take advantage of it, and how it may have just a slight impact on the industry by providing rifles with the same weight, design, size, and ergonomics of an AR15 - using all AR15 compatible parts except the receiver set, the magazine and the mag catch, but with cartridges that none can compete with from a standard AR15.

Let's say that perhaps a company is considering designing an entirely new rifle platform around this metal magazine.

Let's say that these metal magazines will not cost much more than the currently available Magpul Pmags for the platform.

Let's say that said company is currently discussing with and seeking additional distributors and dealers to solidify the supply chain.

Let's say that once the tooling is funded, magazines would be "on shelves" about 6 months later.

Let's say the company is considering crowd-funding the tooling, and providing those that contributed magazines at a discount for their contribution to get the project off the ground.

Let's just say, hypothetically, that all of the above were accurate.

Would you give this a "Meh", or would you give this a "I'll take a few"?

Asking for a friend.

That is true, and it would be fair to say that initially the Grendel version is capable of running them, although not flawlessly, but if the project were to get off the ground, producing that third version would not be difficult.__________________

Would these mags be able to hold the 5.56 parent cased cats such as the 357AR? The base diameter difference is only .044", so I think it should, but want those with experience to weigh in. It would be nice to be able to load the 357AR a little longer also.__________________Gun control is like trying to eliminate drunk driving by making it illegal for sober people to own cars.

No... 5.56 and .308 case-body mags will come later. The Grendel mag should be able to run the .308 cases somewhat well, but not perfect.

Starting out with SPC and Grendel case bodies makes the most sense from a business perspective.__________________

So if I'm understanding this thought experiment correctly, this would, hypothetically, mean someone building a new semi-auto sporting rifle would have the option to get a longer COAL mag for various chambers while still using 95% standard AR-15 pattern parts without selling their firstborn for LWRC's exorbitant receiver set?__________________Always fear the man with nothing to lose.

You understand, hypothetically, correct. It still won’t be a $90 lower & upper set; but nor will it require selling a kidney. It is a NEW family of MSR, while using a very high percentage of standard AR15 parts. Hypothetically...__________________Sua Sponte | Ranger Joe

If you don't know who they are, you should. They are working on them now.

Receiver sets (lower and upper) will be ~$275.00 Retail, and here's the specs:

Machined from 7075-T6 aircraft grade billet aluminum Matte black hard-coat anodized per Mil 8625 Type 3 Class 2 Precision broached magazine well with beveled feed lips Machined and engraved to be compatible with 45 and 60 degree short throw fire control selectors such as the BAD_ASS ST 45 Lever Caliber marking of “Multi” so it can be used with many different caliber uppers *Compatible with all standard AR-15 components and magazines and most aftermarket parts Take down pin spring and detent hole is threaded for a 6-32 set screw for easy capturing (hardware included) Upper tension screw behind grip screw (threaded hole with hardware included) to adjust any “slop” out of vertical fit between upper and lower Ambidextrous trigger finger rests with grooves (above and below mag release / mag catch) *Compatible with Norgon and other aftermarket ambidextrous mag releases Threaded bolt catch pin (Threaded hole and hardware) Integrated large opening “winter” trigger guard Manufactured to MILSPEC on state of the art CNC equipment for consistent quality parts and exacting tolerances

*(Please understand some of the specs listed like "compatible with standard AR15 magazines" will get adjusted)

CLARIFICATION - THESE ARE NOT THE SIX8 COMPATIBLE SETS - DO NOT BUY THESE FOR THE NEW MAGAZINES, THEY WILL BE JUST LIKE THESE WHEN THEY ARE DONE MAKING THEM!

Here's the links to their C4 Billet Lowers and Uppers (Examples)! Receiver sets will come with he mag catch and accept our Metal Magazines as well as the original SIX8 Pmag!

That's a nice price, considering Sulzer sells their Six8 compatible sets for $350. And as those New Frontier uppers look like the F/A assembly is bolted on, does that mean you can replace it with a slick side panel?__________________Always fear the man with nothing to lose.

Please see clarification in my post above about the receiver sets - perhaps I should have worded it better, already getting guys asking if they should buy the C4's I posted as an example.__________________
